A 58-year-old African American female, who had previously undergone a valve-sparing aortic root replacement for a type A dissection, represented 2 months later with a new focal dissection and aneurysm with intramural hematoma just distal to the origin of the left subclavian artery. Since no landing zone distal to the subclavian artery existed, the patient underwent thoracic endovascular aortic repair with laser fenestration-aided stent-graft placement in the left subclavian artery. The patient recovered without complication, and 52 months later, she is doing well with normal renal function and ambulatory status...

BACKGROUND: This study aimed to evaluate the clinical outcomes of aortic root replacement(ARR) surgery:Root reimplantation as valve-sparing root replacement(VSR) and the Bentall procedure. METHODS: We retrospectively reviewed 216 patients who underwent ARR between 1995 and 2013 at Samsung Medical Center. Patients were divided into two groups, depending on the procedure they underwent: Bentall(n=134) and VSR(n=82). The mean follow-up duration was 100.9±56.4 months...

We describe a case of Type A aortic dissection in a 25 year old lady who had undergone a Ross Procedure for aortic valve endocarditis 13 years previously. She was pregnant and noted to have significant enlargement of the aortic root during the latter portion of the third trimester of her pregnancy. An echocardiogram performed after delivery demonstrated new aortic valve insufficiency in addition to an aortic root diameter of 6.5 cm. A CT angiogram demonstrated a Type A aortic dissection involving only the very proximal portion of the ascending aorta...

We devised a simple modification of the Florida Sleeve procedure to perform aortic valve-sparing surgery. This technique is simple, quick, effective, and safe. We used this technique in operations performed on two young patients with Marfan syndrome. The initial and short-term results were satisfactory.

OBJECTIVE: Autograft dilatation is the main long-term complication following the Ross procedure using the freestanding root replacement technique. We reviewed our 25-year experience with the Ross procedure with a special emphasis on valve-sparing reoperations. METHODS: From 1991 to 2016, 153 patients (29.6 ± 16.6 years; 29.4% pediatric) underwent a Ross operation at our institution with implantation of the autograft as freestanding root replacement. The follow-up is 98...

OBJECTIVES: Most patients (75%) with Marfan syndrome present with aortic root dilatation that may require surgical intervention. However, associated cardiovascular disorders are not limited to the aortic root. These patients frequently require consecutive operations on the remaining thoracic aorta or the heart valves. Our intent was to characterize the spectrum of such procedures. METHODS: Data from all patients with Marfan syndrome undergoing aortic root surgery at our centre between 1988 and 2016 were analysed retrospectively...

Ninety-nine patients underwent valve sparing aortic root replacement, mostly using reimplantation technique. Mean age was 56.1±13.4 years. Indication of this type of operation was extended to patients with significant aortic regurgitation (AR) accompanied by sinus Valsalva diameter more than 40 mm. Bicuspid valve presented in 17 patients. The proportion of severe AR was 55%. Valve plasty technique included central plication (n=61) and pericardial patch (n=7). Operative mortality was 1%. AR grade at discharge was none or trivial in 87 patients (88%)...

Valve-sparing root replacement is increasingly used to overcome drawbacks associated with valvular prostheses. In our institution, 7 patients underwent valve-sparing root replacement from August 2016 to July 2017. The mean age was 45 years (range, 14~69 years). Three patients had Marfan syndrome and 1 had Loeys-Dietz syndrome with acute aortic dissection. All patients underwent surgery with reimplantation technique using a Valsalva graft. Two patients required repair of aortic valve leaflet prolapse. All patients had an excellent clinical course, with mild or no aortic regurgitation and a decrease in end-diastolic volume on echocardiography...

BACKGROUND: The Bentall procedure is a reliable treatment of various types of aortic root pathology. Furthermore, the aortic valve-sparing aortic root replacement also has been accepted as an ideal procedure especially in young patients. Recently, we have developed a simple valve-sparing operation focused on standardization and reproducibility. METHODS: From 2011 to 2017, 44 consecutive patients underwent aortic root replacement( Bentall 17, David 27)in our institution...

A 13-year-old male presented with neoaortic root dilatation and severe aortic valve regurgitation 13 years following an arterial switch operation. The valve cusps were unbalanced due to an enlarged non-coronary cusp. A valve-sparing reimplantation with a cusp plication was performed which resulted in a competent valve with trivial regurgitation. Thus, even in an unbalanced cusp, valve-sparing reimplantation can be used for neoaortic root dilatation and valve regurgitation after an arterial switch operation.

OBJECTIVES: Remodelling with extra-aortic ring annuloplasty has emerged as an alternative approach to root reimplantation. However, no studies have yet compared outcomes between procedures. The aim of this study was to compare mid-term outcomes in patients undergoing reimplantation versus remodelling with extra-aortic annuloplasty. METHODS: From 2001 to 2017, 142 patients underwent root remodelling with extra-aortic annuloplasty (n = 83, 48 ± 13 years) or a reimplantation technique (n = 59, 48 ± 12 years) at the Montreal Heart Institute...

OBJECTIVES: This study was undertaken to evaluate the flow dynamics in the aortic root after valve-sparing root replacement with and without neosinuses of Valsalva reconstruction, by exploiting the capability of 4D Flow imaging to measure in vivo blood velocity fields and 3D geometric flow patterns. METHODS: Ten patients who underwent valve-sparing root replacement utilizing grafts with neosinuses or straight tube grafts (5 cases each) were evaluated by 4D Flow imaging at a mean of 46...

OBJECTIVES: To investigate the long-term durability of aortic valves, we reviewed the outcomes of patients who underwent valve-sparing root replacement with acute Type A aortic dissection. METHODS: We included patients who underwent emergent aortic repair for acute Type A aortic dissection at our university hospital between 2000 and 2016. We identified patients who underwent valve-sparing root replacement from the included cohort and assessed their survival and long-term valve durability...

OBJECTIVE: Remodeling or reimplantation are established operative techniques of aortic valve-sparing root replacement. Long-term follow-up is necessary comparing tricuspid and bicuspid aortic valves. METHODS: A total of 315 patients (tricuspid, n = 225, bicuspid, n = 89, quadricuspid, n = 1; remodeling, n = 101, reimplantation, n = 214) were evaluated. Mean follow-up was 10.1 ± 5.6 and 6.4 ± 4.2 years for the remodeling and reimplantation group, respectively...
